GLOSSARY

Become familiar with these terms before operating the

unit.

CFM: Cubic feet per minute.

SCFM: Standard cubic feet per minute; a unit of

measure of air delivery.

PSIG: Pounds per square inch gauge; a unit of meas-

ure of pressure.

ASME: American Society of Mechanical Engineers;

made, tested, inspected and registered to meet the

standards of the ASME.

Code Certification: Products that bear one or more

of the following marks: UL, CUL, ETL, CETL, have

been evaluated by OSHA certified independent safety

laboratories and meet the applicable Underwriters

Laboratories Standards for Safety.

Cut-In Pressure: While the motor is off, air tank

pressure drops as you continue to use your accesso-

ry. When the tank pressure drops to the factory set

low pressure the motor will restart automatically. The

low pressure at which the motor automatically restarts

is called “cut-in” pressure.

Cut-Out Pressure: When an air compressor is

turned on and begins to run, air pressure in the air

tank begins to build. It builds to a factory set high

pressure before the motor automatically shuts off -

protecting your air tank from pressure higher than its

capacity. The high pressure at which the motor shuts

off is called “cut-out” pressure.

GROUNDING INSTRUCTIONS

RISK OF ELECTRICAL

SHOCK. In the event of a

short circuit, grounding reduces the risk of

shock by providing an escape wire for the

electric current. This air compressor must be

properly grounded.

The portable air compressor is equipped with a cord

having a grounding wire with an appropriate ground-

ing plug (see following illustrations). The plug must be

used with an outlet that has been installed and

grounded in accordance with all local codes and ordi-

nances.

1. The cord set and plug with this unit contains a

grounding pin. This plug MUST be used with a

grounded outlet.

IMPORTANT: The outlet being used must be installed

and grounded in accordance with all local codes and

ordinances.

2. Make sure the outlet being used has the same

configuration as the grounded plug. DO NOT USE

AN ADAPTER. See illustration.

3. Inspect the plug and cord before each use. Do

not use if there are signs of damage.

4. If these grounding instructions are not completely

understood, or if in doubt as to whether the com-

pressor is properly grounded, have the installation

checked by a qualified electrician.

INSTALLATION

HOW TO SET UP YOUR UNIT

Location of the Air Compressor

Locate the air compressor in a clean, dry and well

ventilated area. The air compressor should be located

at least 12" away from the wall or other obstructions

that will interfere with the flow of air. The air compres-

sor pump and shroud are designed to allow for proper

cooling. The ventilation openings on the compressor

are necessary to maintain proper operating tempera-

ture. Do not place rags or other containers on or near

these openings.The air filter must be kept clear of

obstructions which could reduce air flow to the air

compressor.

IMPROPER GROUNDING

CAN RESULT IN ELEC-

TRICAL SHOCK.

Do not modify the plug provided. If it does

not fit the available outlet, a correct outlet

should be installed by a qualified electri-

cian.

Repairs to the cord set or plug MUST be

made by a qualified electrician.

Extension Cords

Use extra air hose instead of an extension cord to

avoid voltage drop and power loss to the motor, and

to prevent overheating.

If an extension cord must be used, be sure it is:

• a 3-wire extension cord that has a 3-blade

grounding plug, and a 3-slot receptacle that will

accept the plug on the product

• in good condition

• no longer than 50 feet

• 12 gauge (AWG) or larger. (Wire size increases as

gauge number decreases. 10 AWG and 8 AWG

may also be used. DO NOT USE 14 OR 16

AWG.)

Voltage and Circuit Protection

Refer to the Parts Manual for the voltage and mini-

mum branch circuit requirements.

Certain air compressors can be operated on a 15 amp

circuit if the following conditions are met.

1. Voltage supply through branch circuit is 15 amps.

2. Circuit is not used to supply any other electrical

needs (lights, appliances, etc.).

3. Extension cords comply with specifications.

4. Circuit is equipped with a 15 amp circuit breaker

or 15 amp time delay fuse. NOTE: If compressor

is connected to a circuit protected by fuses, use

only time delay fuses. Time delay fuses should be

marked “D” in Canada and “T” in the US.

If any of the above conditions cannot be met, or if

operation of the compressor repeatedly causes inter-

ruption of the power, it may be necessary to operate it

from a 20 amp circuit. It is not necessary to change

the cord set.

10 - ENGD22130

OPERATION

Description of Operation

Become familiar with these controls before operating

the unit.

On/Auto/Off Switch: Turn this switch ON to provide

automatic power to the pressure switch and OFF to

remove power at the end of each use.

Pressure Switch: The pressure switch automatically

starts the motor when the air tank pressure drops

below the factory set “cut-in” pressure. It stops the

motor when the air tank pressure reaches the factory

set “cut-out” pressure.

Safety Valve: If the pressure switch does not shut off

the air compressor at its “cut-out” pressure setting,

the safety valve will protect against high pressure by

“popping out” at its factory set pressure (slightly high-

er than the pressure switch “cut-out” setting).

Outlet Pressure Gauge: The outlet pressure gauge

indicates the air pressure available at the outlet side

of the regulator. This pressure is controlled by the reg-

ulator and is always less than or equal to the tank

pressure.

Tank Pressure Gauge: The tank pressure gauge

indicates the reserve air pressure in the tank.

Regulator: Controls the air pressure shown on the

outlet pressure gauge. Pull the knob out and turn

clockwise to increase pressure and counterclockwise

to decrease pressure. When the desired pressure is

reached push knob in to lock in place.

Drain Valve: The drain

valve is located at the

base of the air tank and is

used to drain condensa-

tion at the end of each

use.

Cooling System (not shown): This compressor con-

tains an advanced design cooling system. At the heart

of this cooling system is an engineered fan. It is per-

fectly normal for this fan to blow air through the vent

holes in large amounts. You know that the cooling

system is working when air is being expelled.

Air Compressor Pump (not shown): Compresses air

into the air tank. Working air is not available until the

compressor has raised the air tank pressure above

that required at the air outlet.

Check Valve: When the air

compressor is operating, the

check valve is “open”, allow-

ing compressed air to enter

the air tank. When the air

compressor reaches “cut-

out” pressure, the check

valve “closes”, allowing air pressure to remain inside

the air tank.

Pressure Release Valve: The

pressure release valve located

on the side of the pressure

switch, is designed to auto-

matically release compressed

air from the compressor head

and the outlet tube when the

air compressor reaches “cut-

out” pressure or is shut off. The pressure release valve

allows the motor to restart freely. When the motor

stops running, air will be heard escaping from this

valve for a few seconds. No air should be heard leak-

ing when the motor is running, or continuous leaking

after unit reaches “cut-out” pressure.

How to Start

1. Turn the On/Auto/Off lever to “AUTO” and allow

tank pressure to build. Motor will stop when tank

pressure reaches “cut-out” pressure.

2. Pull the regulator knob out and turn clockwise to

increase pressure. When the desired pressure is

reached push knob in to lock in place. The com-

pressor is ready for use.

NOTE: Always operate the air compressor in well-

ventilated areas free of gasoline or other combustible

vapors. If the compressor is being used to operate a

sprayer DO NOT place near the spray area.

Before Starting

Break-in Procedure

Serious damage may result if the

following break-in instructions are

not closely followed.

This procedure is required before the air compressor

is put into service and when the check valve or a

complete compressor pump has been replaced.

1. Make sure the On/Auto/Off lever is in the "OFF"

position.

NOTE: If hose end adapter was replaced with quick

connect, pull coupler back until it clicks to prevent air

from escaping through the quick connect.

Plug the power cord into the correct branch circuit

receptacle.

(Refer to Voltage and Circuit

Protection paragraph in the Installation section of

this manual.)

3. Open the drain valve

fully (counter-clock-

wise) to permit air to

escape and prevent air

pressure build up in

the air tank during the break-in period.

How to Use Your Unit

How to Stop:

1. Set the On/Auto/Off lever to “OFF”.

until it stops. Push knob in to lock in place.

3. Attach hose and accessories. NOTE: The hose or

accessory will require a quick connect plug if the

air outlet is equipped with a quick connect.

Too much air pressure

causes a hazardous risk of

bursting. Check the manufacturer’s maximum

pressure rating for air tools and accessories.

The regulator outlet pressure must never

exceed the maximum pressure rating.

4. Move the On/Auto/Off lever to "ON/AUTO" posi-

tion. The compressor will start.

5. Run the compressor for 15 minutes. Make sure

the drain valve is open and there is minimal air

pressure build-up in tank.

To Check Safety Valve

If the safety valve does

not work properly, over-

pressurization may occur, causing air tank

rupture or an explosion. Before starting com-

pressor, pull the ring on the safety valve to

make sure that the safety valve operates

freely. If the valve is stuck or does not operate

smoothly, it must be replaced with the same

type of valve.

To Drain Tank

1. Set the On/Auto/Off lever to “OFF”.

2. Pull the regulator knob out and turn clockwise to

set the outlet pressure to zero.

3. Remove the air tool or accessory.

4. Pull ring on safety valve allowing air to bleed from

the tank until tank pressure is approximately 20

psi. Release safety valve ring.

5. Drain water from air tank by opening drain valve

(counter-clockwise) on bottom of tank.

Water will condense in the

air tank. If not drained,

water will corrode and weaken the air tank

causing a risk of air tank rupture.

Frequently

●

NOTE: See “Operation” section for the location of controls.

To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule should

be prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working

environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions

under which your compressor is used. The modifications will depend upon the hours of operation and the work-

ing environment. Compressor outfits in an extremely dirty and/or hostile environment will require a greater fre-

quency of all maintenance checks.

Unit cycles automatically when power is on. When performing maintenance, you may

be exposed to voltage sources, compressed air, or moving parts. Personal injuries

can occur. Before performing any maintenance or repair, disconnect power source from the compressor

and bleed off all air pressure.

NOTE: If the air filter is extremely dirty it will need to

be replaced. Refer to the “Repair Parts” for the cor-

rect part number.

Motor

The motor has an automatic reset thermal overload

protector. If the motor overheats for any reason, the

overload protector will shut off the motor. The motor

must be allowed to cool down before restarting. The

compressor will automatically restart after the motor

cools.

If the overload protector shuts the motor off frequent-

ly, check for a possible voltage problem. Low voltage

can also be suspected when:

1. The motor does not get up to full power or speed.

2. Fuses blow out when starting the motor; lights

dim and remain dim when motor is started and is

running.

Air Compressor Pump Intake and Exhaust

Valves

Once a year have a Trained Service Technician check

the air compressor pump intake and exhaust valves.

6. Using an adjustable wrench loosen pressure relief

tube nut at air tank. Carefully move pressure relief

tube away from check valve.

7. Unscrew the check valve (turn counterclockwise)

using a 7/8” open end wrench. Note the orienta-

tion for reassembly.

8. Using a screwdriver, carefully push the valve disc

up and down. NOTE: The valve disc should move

freely up and down on a spring which holds the

valve disc in the closed position, if not the check

valve needs to be cleaned or replaced.

9. Clean or replace the check valve. A solvent, such

as paint or varnish remover can be used to clean

the check valve.

10. Apply sealant to the check valve threads. Reinstall

the check valve (turn clockwise).

11. Replace the pressure release tube. Tighten nut.

12. Replace the outlet tube and tighten nut.

13. Replace the shroud and air filter.

14. Perform the Break-in Procedure. See “Break-in

Procedure” in the Operation section.

SERVICE AND ADJUSTMENTS

Unit cycles automatically when power is on. When doing Maintenance, you may be exposed

to voltage sources, compressed air or moving parts. Personal injuries can occur. Before per-

forming any Maintenance or repair, unplug the compressor and bleed off all air pressure.

ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE PERFORMED BY

TRAINED SERVICE TECHNICIAN.

To Replace or Clean Check Valve

1. Release all air pressure from air tank. See “To

Drain Tank” in the Maintenance section.

2. Unplug outfit.

3. Using a phillips screwdriver remove the air filter

cover.

4. Remove the rear shroud using T-20 torx wrench.

5. Using an adjustable wrench loosen outlet tube nut

at air tank. Carefully move outlet tube away from

check valve.

Before servicing:

●Unplug or disconnect electrical supply to the

air compressor.

●Bleed tank of pressure.

●Allow the air compressor to cool.

STORAGE

Before you store the air compressor, make sure you

do the following:

1. Review the "Maintenance" section on the preced-

ing pages and perform scheduled maintenance as

necessary.

2. Set the On/Auto/Off lever to “OFF”.

3. Turn the regulator counterclockwise and set the

outlet pressure to zero.

4. Remove the air tool or accessory.

5. Pull ring on safety valve allowing air to bleed from

the tank until tank pressure is approximately 20

psi. Release safety valve ring.

6. Drain water from air tank by opening drain valve

on bottom of tank.

Water will condense in the

air tank. If not drained,

water will corrode and weaken the air tank

causing a risk of air tank rupture.

7. After the water has been drained, close the drain

valve.

NOTE: If drain valve is plugged, release all air pres-

sure. The valve can then be removed, cleaned, then

reinstalled.

8. Protect the electrical cord and air hose from dam-

age (such as being stepped on or run over). Wind

them loosely around the compressor handle (If so

equipped).

Store the air compressor in a clean and dry location.

TROUBLESHOOTING

Performing repairs may expose voltage sources, moving parts or compressed air sources,

moving parts or compressed air sources. Personal injury may occur. Prior to attempting any

repairs, unplug the air compressor and bleed off all air tank air pressure.

PROBLEM CAUSE CORRECTION

Pressure switch does not shut off

motor when compressor reaches

“cut-out” pressure.

Pressure switch “cut-out” too

high.

Move On/Auto/Off lever to the

“OFF” position, if the outfit does

not shut off contact a Trained

Service Technician.

drop to occur. If there is an excessive amount of

pressure drop when the accessory

is used, adjust the regulator fol-

lowing the instructions in the

“Description of Operation” para-

graph in the “Operation Section.

NOTE: Adjust the regulated pres-

sure under flow conditions (while

accessory is being used).
